PLUMBING JOINT-FITTING AND ATTACHMENT.

Specification of Letters Patent.

Patented Nov. 2, 1909.

7 Application its November 29, 1907. Serial No. 404,276.

and Fancy M. Fons'run, citizens of the l nited States. residing at Berkeley, in the county of .-\laniedav and State of California,

have invented new and useful improvements in Plumbing Joint'Fittuigs and Attachments, of which the following is a. specification.

Our invention relates to forming joint attaclnnents which are especially designed where connections are to be made through floors, and its object is to render said connections more convenient, accessible and safe from loss.

It consists in a combination and arrangement of parts which will lie-more tully eX- plained by reference to the accompanying t 1 Fa wings.

Figure l is a sectional view of the device as applied. Fig. 2 is a plan .view. Fig. 3 is a detail view of the fastening screw.

In Patent 3 0. 858,865 issued to us July 2, 1907, we have shown a closet bowl or other device having what is termed a. floor flange, and a joint fitting tot-onnect said bowl discharge with the escape pipe or conductor, and form a joint therewith; said joint flange being. titted to and secured beneath the floor flange of the bowl. The connection between these two is usually ctlected by bolts entered from below, and having nuts upon theupper ends by which'to secru'e the parts together. If it is necessary or desirable to remove the bowl the nuts are first unscrewed, and under ordinary conditions the bolts are liable to drop out, and be lost in the space below the floor, and when such fitting is employed in conjunction with joints which have to be calked, it is dithcult to obtain access to such joints on ac count of the flange of the fitting being interposed. v I

In our present invention, we make the fitting A with an interior coucavod groove at the junction of the body of the fitting and the flange, and within this groove is titted a gasket which is compress d between the junction of the angli and the bowl flange to form a tight. joint. As it is frequently desirable to introduce a calltiug tool to form a joint at some point beneath these flanges, we have shown the flange 2 of the fitting as cut away upon two sides, leaving a sutlicient. portion of the flange, preferably upon the bowl flange. The space thus left between the ends of the flange segments, is sufiicient' for the introducing ot. the callting tool, and to give acce s to the joints'or parts beneath. 'ihese flanges remaining on the fitting serve for its nutclnnent to the bowl flange by bolts l and nuts 5, and in order to prevent the dropping and loss ofthesc bolts when the nuts are removed, We have shown the following means for securing them in place: Each of the flanges has a semi-circular slot (3 made in it, and at one end the slots are enlarged sutiiciently to admit the bolt and a shouldered portion 7 which lies between the screw-threaded portion of the bolt and the head 8. Between this shoulder 7 and the head 8 is a, flattened or rectangular portion 9, of less diameter than the shoulder or flange 7 and head 8.

With this construction it will be seen that the bolt can be introduced through the enlarged end of the slot, the flange 7 passing.

'through this enlargement, but the head 8 being large enough not to pass through, the bolt is then slippedv along into the segmental channel, and the part 9 substantially fitting this channel, the flange or shoulder 7 projects so that the bolt is confined in the slot inthe flange of the fitting, and cannot be removed therefrom without turning the fitting flange or moving the bolt, until the bolt is again in line with the larger portion of the slot or opening. It will thus be seen that the nuts can be safely removed from the upper end of the bolt without danger of the bolt dropping out.

Having thus described our invention, what we claim and desire to secure by Letters Patent isl. The combination with a bowl and a soil-pipe, of a ferrule for coupling the bowl to the soilpipc, the ferrule being of smaller diameter than the soil-pipe, and provided with a flange extending over the top of the soibpipe, the flange having arc-shaped open portions to permit the introduction of packing between the. ferrule and the soil-pipe and means for securing the bowl to the flange of the ferrule.

2. The combination with a bowl and a soil pipe having an enlarged head substantially in line with and at a. distance below the bowl, of an extension piece adapted to tit the head of the. soil pipe, at screw-threaded sleeve tilting the upper end of the extension opposite sides of the fitting, to secure it to t piece, and having a flange with arc-shaped open portions to permit the introduction of packing between the extension piece and the soil pipe, and means for securing the bowl to the flange of the connecting sleeve.

3. The combination with a bowl and a soil pipe, of an extension piece for coupling the bowl to the soil pipe, at flange screwed to the extension piece and registering with the base of the bowl, said flange having areshaped open portions to permit the introduction of packingbetween the extension piece and the soil pipe.

4. The combination with a bowl and a soil pipe having an enlarged upper end, of a ferrule for couplin the bowl to the soil pipe. the ferrule being of smaller diameter than the enlarged end of the soil pipe, and provided with a flange extending over the top of the soil-pipe, said flange having arcshuped open portions to permit the introduction of packing between the ferrule and the soil pipe, and means for securing the bowl to the flange of the ferrule.

In testimony whereof we have hereunt'. set our hands in presence of two subscribing 25 w i tn esses.
